Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Objectives:
- Fedora 16 Desktop to authenticate using RHEL5 (control user access to the desktop)
- Upon successful logon, user will have a home drive to store his/her own files.
- Many different users will be using this Fedora 16 Desktop but only authorize user can login

I would also veeeerrrrryyy strongly suggest you take the time out to appreciate the independent parts of a solution like this. It's lots of small things that just happen to coincidence with each other, not one large thing...

they build up to provide a user experience, but LDAP would never have anything to do with NFS, they just happen to both be there at the same time.

both the stages of ldap config can be started with the system-config-authentication tool if you wish, but it's very seldom up to the task of fully completing the job, so I'd recommend going direct to the pretty well commented config files.

I have limited knowledge on OpenLDAP, only got the basic configuration working, adding, modifying and deleting user.
Will explore more on this OpenLDAP and NFS.
See how it goes. I will re-post here if I encounter any specific problems.

So what is logged in /var/log/messages / /var/log/secure ? Is there an LDAP query happening here? tcpdump can be useful to ensure your ldap server is actually being hit, as well as loking at the ldap server logs of course.

I am truthfully sorry if I offended/annoyed anyone with these. (Removed Red Text and * and CAPS)

I was trying to be make it clear with red text of my reply in the jungle of black text, no other meaning.

I have since install a brand new Fedora client and re-try, I thought I messed up the 1st one.

Strange, I am able to do a ldapsearch from Fedora to RHEL but got ldaps bind error on Fedora machine.

well the first log shows LDAP, the second shows LDAPS, so there's clearly a significant difference there, which could mean things like iptables not being open, or slapd not listening on 636. Generally STARTTLS is preferred over LDAPS these days, so you should only really need port 389 for plain and encrypted binds.
